DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

A plurality of different embodiments of the invention is shown in theFigures of the application. Similar features are shown in the variousembodiments of the invention. Similar features have been numbered with acommon reference numeral and have been differentiated by an alphabeticsuffix. Also, to enhance consistency, the structures in any particulardrawing share the same alphabetic suffix even if a particular feature isshown in less than all embodiments. Similar features are structuredsimilarly, operate similarly, and/or have the same function unlessotherwise indicated by the drawings or this specification. Furthermore,particular features of one embodiment can replace corresponding featuresin another embodiment or can supplement other embodiments unlessotherwise indicated by the drawings or this specification.

The invention, as demonstrated by the exemplary embodiments describedbelow, can provide a construction-grade hand winding/storage device,with adjustable/selectable winding region lengths and interchangeablewinding fork accessories. Embodiments can simplify and ease winding,carrying, storing, and removing electrical power cords, hoses, ropes,and other elongated objects.

In the exemplary embodiment, a rigid member can be a construction graderod that can withstand impact, twisting, and pulling forces. Theexemplary embodiment can accommodate different lengths of wound objects,resulting in more desirable elongated shapes suited to the respectivelengths of the wound object(s). Embodiments can reduce the total numberof wound lengths, twisting, compression, and material fatigue in thewound object.

A fork according to one or more embodiments can be strong and impactresistant. The fork can easily connect to the rigid member. The fork cancradle the wound object and eliminate tangles. The interconnectionbetween the fork and rigid member can be universal, replaceable, and/orinterchangeable. One of the tines of the fork can be rotatable toeliminate the burden of unwinding the object.

FIG. 1 shows an exemplary device 10 for winding elongate flexibleobjects. The flexible object can be an electrical power cord, a hose, orany other kind of flexible, windable, elongated object. The device 10includes a rigid member 12 extending along a central axis 14 betweenfirst and second ends 16, 18.

The rigid member 12 can be a one-piece integrally-formed shaft, hollowor solid. “Integrally-formed” refers to the fact that in the exemplaryembodiment the rigid member can be formed at one time rather than beingformed as separate components that are subsequently joined together. Theterm defines a structural feature since structures that areintegrally-formed are structurally different than structures that arecomprised of subcomponents formed separately and then subsequentlyjoined. “Integral” means consisting or composed of parts that togetherconstitute a whole and thus encompasses structures of more than one partwherein the parts are either integrally-formed or formed separately andthen subsequently joined.

The device 10 also includes a first fork 20 having a base 22 mounted tothe rigid member 12 at the first end 16 of the rigid member 12. Theexemplary rigid member 12 can directly and releasibly engage the firstfork 20, such as through male threads 38 defined by the rigid member 12and female threads (not visible) defined by the base 22.

FIG. 2 shows an alternative embodiment in which rigid member can bedirectly and releasibly engaged with a fork through burrs. A connectingstructure 40 a can be defined a rigid member 12 a. The connectingstructure 40 a is shown in dash line since it is disposed within anaperture 80 a formed in a base 22 a of a fork. The connecting structure40 a can be generally square in cross-section and define burrs oncorners, such as burr 42 a. The base 22 a can also have a squarecross-section. A square cross-section can be desirable to preventrelative rotation between the fork and the rigid member. The burrs, suchas burr 42 a, can dig into the plastic body of the base 22 a duringinsertion of the connecting structure 40 a in the base 22 a. Theinteraction between the burrs and the base 22 a can resist movementbetween the base 22 a and the rigid member 12 a attached to the plasticconnecting structure 40 a. FIG. 2 shows that the aperture 80 a comprisesa flat profile on both sides of a central axis 14 a, the flat profilesreferenced at 104 a and 106 a.

Referring again to FIG. 1, the first fork 20 can have a plurality oftines 24, 26, 28, 30 supported on the base 22. The exemplary tines 24,26, 28, 30 can tine lengths, depths, and tine gaps. A length of tine 30is referenced at 32. A depth of tines 28 and 30 is referenced at 34. Agap between tines 24 and 26 is referenced at 36.

The exemplary tines 26, 28 of the first fork 20 are mounted directly tothe base 22 of the first fork 20. The exemplary tines 24 and 30 of thefirst fork 20 are mounted indirectly to the base 22 of the first fork20. The tine 24 is connected to the base 22 through the tine 26.Further, the tine 24 is connected to the tine 26 through a pivot pin 50.The tine 24 can pivot about the pin 50 along an arc referenced at 52.The pivot axis defined by the pin 50 extends transverse to and spacedfrom the central axis 14. Pivoting of the tine 24 allows an elongateobject held in between the tines 24 and 26 to be removed from the device10 without being unwound. In other words, pivoting of a tine allows forquick-release of the elongate object.

The tines 24 and 26, or the tines 28 and 30, can be viewed as a singletine. Embodiments of the invention can be practiced with numerousconfigurations of tines. The single tine formed by the combination ofthe tines 28 and 30 extends along a torturous path. A “torturous” pathincludes a plurality of direction changes. The single tine formed by thecombination of the tines 24 and 26 also extends along a torturous path.

The device 10 also includes a second fork member having a basereleasibly mounted to the rigid member 12 at the second end 18 of therigid member 12 and a plurality of tines supported on the base. FIG. 1shows several different configurations of forks, fork 20 being a firstconfiguration. It can be desirable that the same configuration of forkbe used at both ends 16, 18 of the rigid member 12 in the exemplaryembodiment. However, identical (or substantially identical) forks arenot required of the broader invention.

In an embodiment having the same configuration of forks at both ends,the first and second forks can be centered on the central axis 14 andeach can be symmetric about the central axis 14. The fork 20 issubstantially symmetric, since the presence of the pin 50 upsets perfectsymmetry. The fork 20 could be made perfectly symmetrical by adding apivot pin between the tines 28 and 30 or by omitting the pivot pin 50between the tines 24 and 26.

FIGS. 1A and 1B show two configurations of alternative forks. A fork 54includes a base 56 and two tines 58, 60. The tine 60 is mounted forpivoting movement relative to the base 56 about a pivot axis 62extending transverse to and intersecting the central axis 14. A fork 64includes a base 66 and two tines 68, 70. A protuberance 72 projectslaterally from the base 22 transverse to and away from the central axis14, in a first direction referenced at 74. The protuberance 72 extendsfurther from the central axis 14 in the first direction 74 than eithertine 68, 70 of the first fork 20. The protuberance 72 can be useful forhanging the device 10 when stored (either with a wound object or withouta wound object). The exemplary protuberance 72 has a wider portion and aneck portion for being received in a bracket with a variable width slot,but could take other forms in other embodiments of the invention, suchas a hook.

An embodiment of the invention could be practiced as a kit including aone or more rigid members and pairs of mating forks. For example, onekit could include rigid member 12, two forks 20, two forks 54, and twoforks 64. Another kit could include rigid members of different lengths.A kit would be desirable to allow the user numerous options in arrangingand storing elongate, flexible objects.

Another feature of the exemplary embodiment is a sleeve 76 encirclingthe rigid member 12 along the central axis 14 between the first end 16and the second end 18. The sleeve 76 can be made of foam, open cell orclosed cell. The sleeve can be made of rubber, silicone, or some otherflexible or rigid plastic. The sleeve 76 can define ribs or othersurface patterns to enhance gripping by the user's hand.

Another feature of the exemplary embodiment is a clamp 78 mounted on oneof the plurality tines. The exemplary clamp 78 is mounted on the tine26. The position of the clamp 78 along the tine 26 is adjustable. Theclamp 78 can be used to retain an end of a flexible elongate object,such as an outlet of an electrical power cord. The exemplary clamp 78can be formed in part as a pipe clamp that encircles the tine 26 can beselectively tightened or loosened. The exemplary clamp 78 can also beformed in part as a hook or as spring-biased pinching arms that canselectively grasp and release a portion of the elongate object.

FIGS. 3 and 4 show an alternative embodiment of the invention. A fork 82b includes tines 84 b, 86 b. The tine 84 b is mounted for pivotingmovement about a pivot axis 88 b that would extend transverse to acentral axis. The tine 84 b is larger than the tine 86 b to make thetine 84 b easier to grasp and rotate. In other words, as clearly shownby FIGS. 3 and 4, the tine 84 b is longer and extends further along thecentral axis 14 b from the base 22 b than the tine 86. FIGS. 3 and 4also show that the first tine 84 b includes a first distal end 92 bremote from the base 22 b and defines a first surface 94 b confrontingthe second tine 86 b. FIGS. 3 and 4 also show that the second tine 86bincludes a second distal end 96 b remote from the base 22 b and definesa second surface 98 bconfronting the first tine 84 b. FIGS. 3 and 4 alsoshow the first and second surfaces 94 b, 98 b are mirrored with respectto one another on opposite sides of the central axis 14 b andcontinuously slope toward one another from the first and second distalends 92 b, 96 b to the base 22 b. FIGS. 3 and 4 also show that theexemplary base 22 b includes a bottom surface 100 b extending betweenthe first and second surfaces 94 b, 98 b of the first and second tines84 b, 86 b and that the bottom surface 100 b is flat and cooperates withthe first and second surfaces 94 b, 98 b to form a channel with atruncated V-shape. Another feature of the exemplary embodiment is a pairof protuberances 72 b, 90 b integrally-formed with the tine 86 b. Theprotuberances 72 b, 90 b can be used to retain an end of a flexibleelongate object, such as an outlet of an electrical power cord. FIGS. 3and 4 also show that the pair of protuberances 72 b, 90 b are spacedfrom one another and each projects from the fork 82 b parallel to thecentral axis 22 b, wherein a gap between the pair of protuberances 72 b,90 b is centered along an axis 102 b that is parallel to the centralaxis 22 b.

It is noted that the various forks shown in this application can beuniversal with respect to a rigid member. In other words, the componentscan be formed such that the forks 20, 54, 64, or 82 b could be engagedwith a particular rigid member. Threads can be the structure forreleasibly interconnecting the structures or burrs could be applied. Itis noted that burrs could be used two or three or more times before afork is replaced.

The tines of a fork used in a particular embodiment of the broaderinvention can be or various lengths. For some elongate members, such ashalf-inch hose, the tines may be longer than the tines of a fork usedfor electrical power cords.
